1 Claim.

This invention relates generally to sprinkling devices and more particularly to a combination nozzle and connecting device for the end of a hose.

All devices of this character, made in accordance with the teachings of the prior art, and with which I am familiar, have provided separately a hose nozzle for directing the flow of fluid and a conventional apertured circular shaped lawn sprinkling member for disposal on a lawn or the like for distributing the water over a considerable area of ground. It has been found that there is very little control of the water passing from the circular sprinklers and usually there is too much water emitted, thereby resulting in the flooding out of grass and other seeds, knocking oil delicate petals of flowers and other plants, especially in greenhouses and nurseries where many delicate plants are growing. These circular sprinklers as now provided cannot be used in many instances because there is too great of an amount of water which passes from the sprinkler to the ground. No suitable adjustable means has heretofore been provided at the sprinkler or near thereto to adjust the amount of flow of the water from the conventional circular shaped sprinkler. No nozzle has heretofore been provided having means for adjusting the flow of water therethrough, means for emitting the water in the form of a cone, and means for vaporizing the water through a swirling of the water in the nozzle, and further means for connecting the nozzle to a circular shaped sprinkler at a remote point from the source of supply or to a fitting in the garden remote from the source of supply.

It is, accordingly, an object of my invention to provide a combined nozzle and adjustable means therein adapted to be directly connected to a circular shaped sprinkler or the like which is simple in construction, economical in cost, eflicient in operation, and economical in manufacture.

Another object of my invention is to provide a novel nozzle with a male connecting portion of a coupling formed on the end thereoi adapted for direct connection to a female snap coupling member.

Another object of my invention is to provide a nozzle having means for controlling the flow of water therethrough to a circular shaped sprinkling member or the like to cause the water emitted from the circular shaped sprinkling member to be in the form of a vapor or mist.

Another object of my invention is to provide a novel construction of a nozzle wherein the flow therefrom can be regulated.

Other objects of my invention will become evident from the following detailed description, taken in conjunction with the accompanying drawings, in which Fig. 1 is a side elevational view of my combined nozzle and male connecting member;

Fig. 2 is a view taken on the line 2-2 of Fig. 1;

Fig. 3 is a side elevational view of a modified form of combined nozzle and connecting member;

Fig. 4 is a diagrammatic view showing my novel combination nozzle and male connecting member for a coupling attached toa Y-connection for regulating the water passing to circular shaped sprinklers; and

Fig. 5 is a side elevational view of a Y-connection for use with my novel combined nozzle and connecting member.

Referring now to the drawings, Figs. 1 and 2 show a nozzle member 1 comprising a generally tubular shaped member 2 having a shoulder 3, a connecting portion 4 having a peripheral groove 5, a knurled portion 6 and an externally 2 threaded portion 1. Internally of the tubular member 2, it is threaded at 8, has a seating portion 9, a reduced aperture l0, and a flared out tapered portion H in the outer end thereof. A valve member l3 of cylindrical shape has a bore [6 extending longitudinally thereof, a seating portion l'l adapted to sealingly engage the seat 9 in the tubular member 2, a threaded portion l8 for threadably engaging the internally threaded portion 8 of the tubular member 2, radially extending apertures l9 leading from the bore IE to the outer side of the valve member l3, and an outwardly extending headed portion 2| on the end of said tubular member 13 adapted to move in the reduced aperture In of the tubular aperture 2 to control the new of water through the nozzle and cause the water to be thrown outwardly along the flared portion ll of the tubular member 2 to cause the water to move from the nozzle in substantially conical shape. It will be evident that the further towards the aperture ID that the enlarged head 2| moves, the water will tend to move and pass from the end oi! the nozzle with the base of the cone formed by the water becoming less and less as the headed end 20 moves into the aperture II and when it reaches the aperture Hi, the water passes from the nozzle in substantially a straight line. The valve member I3 is reduced at 2| to form a small annular swirling chamber 22 between the valve member I3 and the inner nected to the end of the valve member Jil by peening over the outer ends 32 of the cavemenber 13. I v

Attached to the male connecting portion-Moi the tubular member 2, I show a conventional female snap connecting coupling member 4|; coinprising an inner sleeve 4| having radially"extending ball-retaining apertures 42, a washer =g'roove '43, an external threaded portion s44tand a clip retaining groove' i45." A telescoping':locking sleeve 46 moves over gthex-ball retainingzapertures 42 of the'sleeve 4| .and ihas a .camming portion 4L-for =holding. the balls 48 :rdisposed 15in the ball-retaining apertures 42:.in.locking:engage- 'ment "with the peripheral .groove 15 in. ithev connecting portionl l of the tubular member ,2 of the nozzle membertl. iAl'spring-iclipflfi .iscdisposed in the-groove 45 f theisleevefll to limit the movement of the lockingnsleevet lfi.

A substantially v-shapednwasher 52. is disposed" in the groove 43 oithe tubular member I to sealingly engage the taperedportion '53 of the connecting'portion 4 of theftubular member' 2.of the nozzlemember l.. i 1' In operation, the female iconnectingxmern-ber 29 is attached to IthQlfiIldeGf. a, hose and the; other end oftheihose isattached to' afaucetfidasshown ,in.-Figi 3..

It will be evident that the nozzle member I may be connected directly to the female coupling members on the ends of 5 the hose lines 61 and 68 individually or it may be connected directly to a female connecting member on one of the cylindrical shaped lawn sprinklers 69. It has heretofore been necessary 'to'kink the hose or gobackto-the house to shut 10 off the water irrthe hose line in orderto make a connection between the end of the sprinkling hose and a lawn sprinkler after the nozzle is uncrewed from the end of the hose. Hoses were flffquiklyru'ind by these previous methods and my device completely eliminates the kinking of the hoseand unscrewing of the nozzle and also provides adjusting means at the outer end of "the hose toadjust the amount of water being emitted from the lawn sprinkler or sprinklers. By utilizing a nozzle member of my novel design :in the; hoseline, leading to alring prinklerrallia- ;por;.or mistspray may beprovided byiadj ustment of .7 the; nozzle, "thereby-eliminating any *chances of washing out seeds or knocking the pfitals from delicate flowers; orgplants. j p v r In.
